Hello everyone.

I just came back from the range and thought I would share my findings... I was shooting at the 100yrd range, temperature was 30 °C, wind velocity was calm, sky condition was clear. Following are some details on the load.

Brass: Remington R-R reloaded 6 times
Powder: RE-15 / 70.0 gr
Bullet: Hornady .375 225gr SP
Primer: WLRM

I shot 2, 10 shot strings through my Pro Chrono Digital chronograph. It was interesting to see the change in velocity as the barrel got hotter and hotter. What I've noticed with the lighter bullets in my barrel, and the 225gr are no exception, well... they don't group as well as the heavier bullets! Some details on the chronograph readings...

First 10 shot string.

HI: 2760 FPS
LO: 2629 FPS
Average: 2721 FPS
Extreme Spread: 131 FPS
Standard Deviation: 35 FPS

Second 10 shot sting.

HI: 2807 FPS
LO: 2715 FPS
Average: 2756 FPS
Extreme Spread: 92 FPS
Standard Deviation: 31 FPS

What's interesting to notice is that, as the barrel and ammunition got warmer, the velocity increased, as one would expect, but the extreme spread dropped.

As far as my groups... well, nothing much to brag about. I had a bad day at the range Rolling Eyes ! I will blame it on the hot weather Very Happy

Moral of the story, my barrel loves the 260gr Accubonds, and not so much the lighter bullets.

I've added a few pictures taken today. For the ones out there who like my new stock, its an Accurate Innovations.

Nice and private setting at that range!

A far cry from the zoo at Sibbald!

Frans

Great report as usual Enigma! Thanks for sharing.

I hadn't ever tried those bullets in my 375 H&H. Interesting results.

Cheers,

The "zoo" at Sibbald, is a public range along HW 66, well, about 8 km south of it, that is being maintained by a couple of private gun clubs, adjacent to it.

If you happen to get there on a weekday, during the hours that normal people are working, you may have some quiet time, and sometimes even the range to yourself. Even though I seriously doubt that the distances between 0-100 and 100-200 are the same, and the 300 meter target is somewhere halfway up a hill in the trees (and you always wonder "does everybody back at the firing line realize I'm in the shrubs here trying to check my targets"), in those cases it provides what you need: a shooting bench and a backstop.

Go there on the weekend, and sometimes also on weekdays, and you'll find it packed and crowded, and precious few lone and serious shooters. It is more about making noise, hooting and hollering and bothering everybody else at the range than about serious shooting. Every bench seems to have a crowd of onlookers of at least half a dozen, there's women and children, and dogs, and cats (not really, haven't seen cats there... yet), and the waiting is endless, for a spot at a bench, for a moment to put up a target, and for a break, so you can go take a peek at the results.

I desperately need to get my rifle ready for sheep season, but I think I will quickly take up a membership in Olds.

Hello Frans,

Thanks for the reply. I have to admit, I did have a very good laugh there's women and children, and dogs, and cats

I have been using 225 Hornadys for culling feral goats,all broadside shots have exited.
Here is one bullet i recovered from a Texas heart at about 20 yards,bullet stopped at the base of the neck.
